Nuffield Trust Senior Fellow Dr Billy Palmer said:
"It is good to see scrutiny of NHS Test and Trace. This programme has a pivotal role to play in controlling Covid-19 and our calculations suggest it will cost the equivalent of £950 per household this year.  Yet the latest data suggest that despite the hard work of its staff, less than one in three of recent close contacts are even asked to self-isolate, well below the level the scientific advisory group thinks is necessary to help suppress the virus. It is frustratingly unclear how many of those contacted actually comply.
"As the report points out, we need to ask questions about NHS T&T's unusual organisational relationships and unclear accountability. The centralised nature of the programme and the limited support and incentives for people to isolate may also be significant problems.
"We desperately need a fully functioning test and trace system - we know that worse performance seems at least to be associated with areas where there are higher cases. This report strengthens the case that we must start by taking a hard look at performance and cost-effectiveness before any third wave hits."
